Reading a console output into QListWidget

Hey i've banging my head over this over a week now!
i need to run a script through Qt GUI app!
this scripts simply lists all the groups in the system( ie. runs /bin/./groups)
now i want this output in the QListWidget!
i run the script using QProcess!
bt im not able to get the output of the script to the GUI
i know i have to use readAllStandardOutput(); bt how???????
pls help me and consider me a noob! :(

[quote author="butterface" date="1402663078"]That's how I always do it:

@
QProcess *testProcessServer = new QProcess();
QStringList argumentsServer;
testProcessServer->setProcessChannelMode(QProcess::MergedChannels);
testProcessServer->start(programServer, argumentsServer);
int status = 0;
if (!testProcessServer->waitForStarted())
{
// do something here
}
textbox->append(QString(testProcessServer->readAll()));
